Original evidence

Mayo Clinic’s magazine interviews Chan, her husband, and her care team. It links no independent clinical report of the episode. [1]

Access and versions

The account leaves the AI product unnamed and does not separate its contribution from rapid access to hospital treatment. The later DISCOVERY study concerns cognition rather than verification of this rescue. [1]
